Subject: arm64: dts: socfpga: agilex7m: Add SoCFPGA Agilex7-M devkit
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=66764673e09b3b9c0e9dc1f785ac9cb7b0e0183a;p=thirdparty%2Flinux.git

arm64: dts: socfpga: agilex7m: Add SoCFPGA Agilex7-M devkit

The Agilex7-M devkit contains an Agilex7M SoC, which is a newly branded
version of the original Agilex SoC. The Agilex7M core peripherals are
identical to the Agilex SoC.

We can re-use the socfpga_agilex.dtsi for this devkit. The Agilex7-M
devkit supports PCIE 5.0(x16), DDR4, DDR5, LPDDR5 and does not have QSPI.
